Garrett Hilyer Lab #1 EEC 100 10/1/2022 Partner: Hai Nguyen Objective: Learn how to use OrCAD to run simulations of a circuit. Be introduced to four key instruments and explore all the various functions that they have to offer. These four instruments consist of: the digital multimeter (DMM), oscilloscope, waveform generator, and triple-output DC supply. TA Sign Off Sheet

The voltages, currents, and power however were very different. I believe this is since the simulation is grounded and the prelab is not.

Conclusion: The data we recorded from our prelab was nearly identical to the data we recorded in section 3.10. When using the prongs to evaluate the circuit drop over a resistor, we found that all our answers were with a tenth of a decimal place.
